' Application filed December 12, 1910. Serial No. 596,894. To all whom it mag concern:

Be it known that I, CASSIUS E. LAMBURTH, a. citizen of the United States, residing at the city'of San Francisco, in the county of San Francisco and- State of California, have invented certain new and useful Improvements iniAeroplanes, of which the following is a specification.

y invention relates to improvements inv aerial vessels. The object of my invention is to provide an air-ship known as an aeroplane which will encounter a minimum of resistance in its passage through the air by reason of the improved shape, position and arrangement of its planes; which has great lane area giving it increased buoyancy, an which has improved .means for compressing air so as to give the vessel unusual stability.

My. invention consists in the novel conof parts shown mthe accompanying drawings, described in the following specification and claimed in the appended claims. a Referring to the accompanying drawings, Figure-Lisa plan view of the vessel embodyingmy invention; Fig. 2 is a side view of said'vesselfat rest; Fig. 3 is a front view ofv sa1d vessel at rest, and Fig. 4 1s a rear VIEW of the same at rest- In the figures 1 represents the frame of the vessel; Steering plane 2 which is located at the 'front'of the vessel is pointed and has a central longitudinal rib depending therefrom which is a peculiar feature of the pointed planes of said aeroplane as shown.= A pointed rear steering rudder 3, being movable to the right or left, is pivotally mounted at 13 and is operated by cord 14 passing. around pulleys 16 leading toany suitable point convenient to the operator. Located on-eachside of the vessel, upper and lower rear planes 4 and '5 and upper and lower front planes 8 and 9 are pointed and have each the depending rib or keel hereinbe'fore mentioned and are secured to the frame as shownin Fig. 2. and 6 extend transversely from the vessel and their front ends are connected to the frame. 'The said Wings 6} are provided near their rear edges-with links 28;.ywhich establish pivotal link connection between the rear part of wings 6 and the rear edges of planes 10, said planes 10 being placed above the Beneath plane 7 wings 6' incidence as the speed of the vessel increases in flight-this is done by the raising of the plane 10 by the air passing under the underside of planes 10 and lifting the outer portion of the rear half of wing 6 through its connection by the link 28, the outer half of wing 6 being particularly Warped during the increase of speed.

Triangular plane 7 being hung centrally to the frame as shown in Fig. 2, the incidence and gravity as operating in the case of said plane are such that should the engine stop while the vessel is in flight, the plane would immediately incline or point-to the earth, causing the vessel to glide down, and said. plane being unobstructed at the top of thevessel, by reason of having the form of a triangle and being inclined as shown in Fi 2 in the operation of the vessel admits freely at its front edges the incoming air and at its rear edge allows such escape of air as to re-- duce at the latter point the volume of such incoming air to about one-half, whereby air is retarded inits rearward movement and compressed under said plane, giving the ves-- sel great stability on account of increase of 85. the under pressure, as this pressure is against the front plane and the arrow pointed planes as well as said plane 7 by reason of similar v constniction and connections as illustrated.

Front plane 2, which is pivotally mounted as shown in Fig. 2, has a steering rod 11 operated bya lever pivoted to the frame, said lever'being marked 27, a cord running from said lever to said rod and designated 12. An engine 26 and a propeller 15 are provided for the vessel, the same having suitable connections. Additional steering wings I? are pivoted outwardly and sidewise on the rear planes 4 and are operated by cord 18 passing over pulley 19 and leading to a suitable. point near the operator. Steering and stopping planes, 20 are positioned on the right and left sidespf the vessel beneath wings 6, and are connected by rods 21 and operated bycord 22 passing over the pulleys 23 and leading to a point nearv and conven ient to' the operator. Flaps 24 are hinged at '25 to wings 6 and are operated in any suit-' able manher,, the same being equalizing planes to brlng'the vessel back .to balance or a. horizontal position. Planes 10 with flaps 2i arc'for lateral balance.

The diagonal braces extendir'" and. eon: nected as shown in Figs. 1 and are arranged so as to give the vessel considerable strength while not adding undue wveight thereto. The cords or wires 12 as connected to steering rod and lever 27, one atthe upper ends thereof and one atthe lower ends thereof enable plane 2 to be inclined .in either direction, being pivoted for. longitudinal balance. The. pointed planes as shown by reason of their acuteness and with heels inclining upwardly to their pointed ends enable the vessel -in its flight to travel with the minimum of resistance while the heels are conducive to balance, one of thefeatures of the vessel being its equilibrium of balance. \Vheels 30 are provided so that the vessel may be moved on the ground.

To operate the vessel the aviator tahes his place in the forepart. of the ship infproximity to the lever 27 from which point he can control the engine and operate the movable wings and planes shown and described as conditions in the air require to accomplish the safe and rapid progress of the machine. The vessel is so arranged that cords or wires may bereadily connected to any of the movable wings or planes thereof leading to the position of the aviator whereby thesame may be operated by him as may be required.

Although I have described in connection with the drawings the construction and relative arrangement of the several elements of my invention. I do not desire to be confined to the same, as such changes may be made as regardsconstruct-ion, arrangement or connection of parts thereof to perform more or less of the functions thereof as referred to asclearly fall within the scope of my inven tion, without departing from the. spirit thereof.
